Bir elektron mikroskobunda, ak\u0131m ta\u015f\u0131yan bobinler manyetik alanlar olu\u015fturur. Bu alanlar mercek gibi davranarak elektron h\u00fczmesini dene\u011fin \u00fcst\u00fcne odaklarlar ve daha sonra bir floresan ekran veya foto\u011fraf plakas\u0131 \u00fczerinde b\u00fcy\u00fct\u00fclm\u00fc\u015f bir g\u00f6r\u00fcn\u00fc olu\u015ftururlar.

Manyetik “mercekler” in teknolojisi, pratikte, elektron dalgalar\u0131n\u0131n kuramsal ay\u0131rma g\u00fcc\u00fcne ula\u015fmas\u0131na izin vermez. \u00d6rne\u011fin, 100 keV’luk elektronlar\u0131n dalga boyu 0.0037 nm’dir. Fakat bunlar\u0131n bir elektron mikroskobundaki ay\u0131rma g\u00fcc\u00fc sadece 0.1 nm civar\u0131ndad\u0131r. Fakat bu yinede bir optik mikroskobun -200 nm’lik ay\u0131rma g\u00fcc\u00fcne g\u00f6re b\u00fcy\u00fck bir geli\u015fedir. Elektron mikroskoplar\u0131 ile 1.000.000 x’in \u00fcst\u00fcndeki b\u00fcy\u00fctmelere eri\u015filmi\u015ftir.<\/p>\n","protected":false},"excerpt":{"rendered":"
